My answer would be save your money for future serice and forget any warranties. Too expensive at this late date.
When we bought the wife a new Subaru Ascent from an out of state dealer in December the push to buy a service contract was monumental. I was prepared but the finance guy was as persistent as any I have experienced. It was from an aftermarket company and since we were financing about half he was building the cost of the contract into the payments. He never gave me a total price but my quick math showed the cost would be close to $5k over 48 months. Each time I said no he would lower it until I finally explained no means no. He was visibily po'd when I told him I would buy nothing but factory backed warranty. He never gave me a price on a Subaru warranty so we signed the papers and left. I ripped them pretty hard on the follow up survey for the heavy handed tactics. The sales part was great but they ruined it with the ordeal they put me thru trying to sell me something I didn't want. If we hadn't sold the wife's vehicle and desperately needed the new one I would have walked.
I did some internet shopping for the Subaru warranty after we got home and found a dealer who was selling the 7 year, 100K mile no deductible warranty for $1550. If it is a factory backed warranty any dealer can sell them and some have much better pricing. I found this out when we bought our Ford F350.
